Mokhoa oa ho Lekola Stator ka Multimeter (Tlhahlobo ea Litsela tse 3)

Alternator, e nang le stator le rotor, e matlafatsa enjene ka ho fetola matla a mochini hore e be motlakase hape e tjhaja betri. Ke ka lebaka lena, haeba ho na le ho hong ho sa tsamaeeng hantle ka stator kapa rotor, koloi ea hau e tla ba le mathata le haeba betri e le hantle. 

Le hoja rotor e ka tšeptjoa, e batla e atisa ho hlōleha hobane e na le li-coil tsa stator le wiring. Ka hona, ho hlahloba stator ka multimeter e ntle ke mohato oa bohlokoa oa ho rarolla mathata. 

Mehato e latelang e tla u thusa ho leka stator ka multimeter ea digital. 

Mokhoa oa ho hlahloba stator ka multimeter?

Haeba u na le bothata ba ho tjhaja koloi kapa sethuthuthu, ke nako ea ho ntša DMM ea hau. 

Taba ea pele, beha DMM ho ohms. Ho feta moo, ha u tšoara lithapo tsa mithara, skrine e lokela ho hlahisa 0 ohms. Ka mor'a ho lokisa DMM, leka betri ka lisebelisoa tsa meter.

Haeba DMM e bala hoo e ka bang 12.6V, betri ea hau e ntle 'me bothata bo ka etsahala ka khoele ea stator kapa terata ea stator. (1)

Ho na le mekhoa e meraro ea ho lekola li-stators:

1. Teko ea Stator static

Teko e tsitsitseng e khothaletsoa haeba u na le bothata ba ho tjhaja koloi kapa sethuthuthu sa hau. Hape, ena ke eona feela teko eo u ka e mathang ha koloi ea hau e sa qale. U ka tlosa stator ho enjene ea koloi kapa ua e leka ka enjene ka boeona. Empa pele u hlahloba litekanyetso tsa ho hanyetsa le ho sheba bokhutšoanyane ba lithapo tsa stator, etsa bonnete ba hore motlakase o tima. (2)

Tekong ea static stator, mehato e latelang e etsoa:

(a) Tima enjene 

Ho hlahloba li-stators ka mokhoa o tsitsitseng, enjene e tlameha ho tima. Joalokaha ho boletsoe pejana, haeba koloi e sa qale, tlhahlobo ea stator static ke eona feela tsela ea ho lekola li-stators. 

(b) Beha multimeter

Beha multimeter ho DC. Kenya lead lead e ntšo ea multimeter ka har'a jack e ntšo ea COM, e bolelang e tloaelehileng. Mohala o mofubelu o tla kena sekoting se sefubelu se nang le matšoao "V" le "Ω". Etsa bonnete ba hore terata e khubelu ha e ea hokeloa sehokelong sa Ampere. E lokela ho ba feela sebakeng sa Volts / Resistance slot.  

Hona joale, ho hlahloba tsoelo-pele, fetola konopo ea DMM ebe u e beha ho letšoao la beep kaha u tla utloa molumo oa molumo ho netefatsa hore ntho e 'ngoe le e' ngoe e nepahetse ka potoloho. Haeba ha o so ka o sebelisa multimeter pele, ka kopo bala bukana ea mosebelisi pele o e sebelisa.

(c) Etsa tlhahlobo e tsitsitseng

Ho hlahloba tsoelo-pele, kenya lisebelisoa tse peli tsa multimeter ka har'a li-sockets tsa stator. Haeba u utloa molumo oa molumo, potoloho e ntle.

Haeba u na le stator ea mekhahlelo e meraro, u lokela ho etsa tlhahlobo ena ka makhetlo a mararo, u kenye li-multimeter probes karolong ea 1 le ea 2, mohato oa 2 le oa 3, ebe joale mohato oa 3 le oa 1. Haeba stator e lokile, u e lokela ho utloa molumo oa molumo maemong ohle.   

Mohato o latelang ke ho hlahloba nako e khutšoanyane ka hare ho stator. Tlosa terata e le 'ngoe ho sokete ea stator ebe u ama khoele ea stator, chassis ea fatše kapa ea koloi. Haeba ho se na molumo oa molumo, joale ha ho na potoloho e khutšoanyane ho stator. 

Joale, ho lekola litekanyetso tsa khanyetso, beha konopo ea DMM ho letšoao la Ω. Kenya li-multimeter lead ho li-sockets tsa stator. Ho bala ho lokela ho ba pakeng tsa 0.2 ohms le 0.5 ohms. Haeba ho bala ho tsoa moeling ona kapa ho lekana le ho se fele, sena ke pontšo e hlakileng ea ho hlōleha ha stator.

Re u eletsa hore u bale bukana ea litšebeletso tsa koloi ea hau ho tseba ho bala ho bolokehileng.

2. Teko e matla ea Stator

Teko e matla ea stator e etsoa ka kotloloho koloing mme e ts'ehetsa multimeter ka mokhoa oa AC. Sena se leka rotor, e nang le limakenete mme e potoloha ho potoloha stator. Ho etsa tlhahlobo e matla ea stator, mehato e latelang e etsoa:

(a) Koala lebone

Ho latela mokhoa o ts'oanang le oa tlhahlobo ea static, kenya multimeter lead ho li-sockets tsa stator. Haeba stator e le mekhahlelo e meraro, tlhahlobo ena e tlameha ho etsoa ka makhetlo a mararo ka ho kenya li-probe ka har'a li-sockets tsa mohato oa 1 le oa 2, mohato oa 2 le oa 3, mohato oa 3 le oa 1. Ha ho tima mollo, ha ua lokela ho nka. 'malo ofe kapa ofe ha o etsa tlhahlobo ena.

(b) Ho khantša ka sesebelisoa sa ho tima

Qala enjene 'me u phete ho khantša ka holimo bakeng sa mekhahlelo e' ngoe le e 'ngoe. Multimeter e lokela ho bonts'a ho bala hoo e ka bang 25V.

Haeba lipalo tsa mekhahlelo efe kapa efe li le tlase haholo, re re ho pota 4-5V, ho bolela hore ho na le bothata ka e 'ngoe ea mekhahlelo mme ke nako ea ho khutlisa stator.

(c) Eketsa lebelo la enjene

Hlakola enjene, eketsa rpm ho isa ho 3000 'me u e hlahlobe hape. Lekhetlong lena multimeter e lokela ho bonts'a boleng ba hoo e ka bang 60 V, 'me e tla eketseha hammoho le palo ea liphetoho. Haeba 'malo o ka tlase ho 60V, bothata bo teng ka rotor. 

(d) Teko ea regulator regulator

Molaoli o boloka motlakase o hlahisoang ke stator ka tlase ho moeli o sireletsehileng. Hokela stator ea koloi ea hau ho molaoli 'me u behe DMM ho lekola li-amps ka sekhahla se tlase. Bulela kgalase le dihloma kaofela ebe o hakolla thapo e mpe ya betri. 

Hokela li-DMM tse etellang pele ka letoto lipakeng tsa palo e mpe ea betri le palo e mpe. Haeba liteko tsohle tse fetileng li ne li lokile, empa multimeter e bala ka tlase ho 4 amps nakong ea teko ena, regulator rectifier e fosahetse.

3. Tlhahlobo ea pono

E tsitsitseng le e matla ke litsela tse peli tsa ho hlahloba li-stators. Empa, haeba u bona matšoao a hlakileng a tšenyo ea stator, mohlala, haeba e shebahala e chesitsoe, ena ke pontšo e hlakileng ea stator e mpe. 'Me ha u hloke multimeter bakeng sa sena. 

Pele u ea, u ka hlahloba tsoa tse ling tse tutorials mona ka tlase. Ho fihlela sehloohong sa rōna se latelang!
